The steps to install PHP8 on Ubuntu are: 1. Update the software package list; 2. Install PHP8 and basic components; 3. Check the version to confirm that the installation is successful; 4. Install additional modules as needed. Windows users can download and decompress the ZIP package, then modify the configuration file, enable extensions, and add the path to environment variables. macOS users recommend using Homebrew to install, and perform steps such as adding tap, installing PHP8, setting the default version and verifying the version. Although the installation methods are different under different systems, the process is clear, so you can choose the right method according to the purpose.

BTC, USDT and USDC are three core assets with complementary functions in the crypto ecosystem. BTC is the "spear" of high risk and high returns, and the goal is wealth growth. Stablecoins are defensive "shields", with the goal of preserving value and providing liquidity. For investors seeking long-term capital appreciation, BTC is the core option. Stablecoins are an essential tool for users who want to flexibly operate, manage risks or earn stable returns in the crypto market, with USDC being more favored by conservative users due to its robustness.

The most popular tracks for new funds currently include re-staking ecosystems, integration of AI and Crypto, revival of the Bitcoin ecosystem and DePIN. 1) The re-staking protocol represented by EigenLayer improves capital efficiency and absorbs a large amount of long-term capital; 2) The combination of AI and blockchain has spawned decentralized computing power and data projects such as Render, Akash, Fetch.ai, etc.; 3) The Bitcoin ecosystem expands application scenarios through Ordinals, BRC-20 and Runes protocols to activate silent funds; 4) DePIN builds a realistic infrastructure through token incentives to attract the attention of industrial capital.

The coordinated rise of Bitcoin, Chainlink and RWA marks the shift toward institutional narrative dominance in the crypto market. Bitcoin, as a macro hedging asset allocated by institutions, provides a stable foundation for the market; Chainlink has become a key bridge connecting the reality and the digital world through oracle and cross-chain technology; RWA provides a compliance path for traditional capital entry. The three jointly built a complete logical closed loop of institutional entry: 1) allocate BTC to stabilize the balance sheet; 2) expand on-chain asset management through RWA; 3) rely on Chainlink to build underlying infrastructure, indicating that the market has entered a new stage driven by real demand.

The duration of the airdrop dividend is uncertain, but the LayerZero, StarkNet and ZK ecosystems still have long-term value. 1. LayerZero achieves cross-chain interoperability through lightweight protocols; 2. StarkNet provides efficient and low-cost Ethereum L2 expansion solutions based on ZK-STARKs technology; 3. ZK ecosystem (such as zkSync, Scroll, etc.) expands the application of zero-knowledge proof in scaling and privacy protection; 4. Participation methods include the use of bridging tools, interactive DApps, participating test networks, pledged assets, etc., aiming to experience the next generation of blockchain infrastructure in advance and strive for potential airdrop opportunities.

Ordinary investors can discover potential tokens by tracking "smart money", which are high-profit addresses, and paying attention to their trends can provide leading indicators. 1. Use tools such as Nansen and Arkham Intelligence to analyze the data on the chain to view the buying and holdings of smart money; 2. Use Dune Analytics to obtain community-created dashboards to monitor the flow of funds; 3. Follow platforms such as Lookonchain to obtain real-time intelligence. Recently, Cangming Money is planning to re-polize LRT track, DePIN project, modular ecosystem and RWA protocol. For example, a certain LRT protocol has obtained a large amount of early deposits, a certain DePIN project has been accumulated continuously, a certain game public chain has been supported by the industry treasury, and a certain RWA protocol has attracted institutions to enter.

Semaphore is used to control the number of concurrent accesses, suitable for resource pool management and flow-limiting scenarios, and control permissions through acquire and release; CountDownLatch is used to wait for multiple thread operations to complete, suitable for the main thread to coordinate child thread tasks. 1. Semaphore initializes the specified number of licenses, supports fair and non-fair modes, and when used, the release should be placed in the finally block to avoid deadlock; 2. CountDownLatch initializes the count, call countDown to reduce the count, await blocks until the count returns to zero, and cannot be reset; 3. Select according to the requirements: use Semaphore to limit concurrency, wait for all completions to use CountDown
